I’ve seen too many teams chasing leads that were never going to buy.

Not because their pitch was bad, but because their data was.

Half the contacts in their CRM were outdated.

The rest had zero buying intent. They were reaching out blindly.

What can change everything for you is adding intent signals on top of enriched data.

Once you know who’s actually looking, everything else, timing, messaging, conversion, becomes ten times easier.

This isn’t about getting more leads.

It’s about getting the right ones.

The ones researching your category, hiring in your space, or comparing tools like yours right now.

Here are the 5 tools to enrich B2B data with buyer intent signals that actually help you find those buyers and keep your data alive.

1. Coldreach – Live buyer intent tracking from 5+ data sources; monitors 79M+ accounts and enriches leads automatically.
   
   

2. Leadsforge – Finds companies showing buying intent (hiring, funding, launches) and delivers verified contacts with proof.
